Figure 1. Identification of a glomerulus, DC4, activated by the CO2 metabolite, carbonic acid.

Figure 1

a, Behavioral testing in a T-maze at permissive (21°C) and non-permissive temperatures (29/34°C). ‘Control’ in this and all subsequent figures refer to responses of flies given a choice between two blank tubes. N=6-8. Error bars: s.e.m. ***P<0.001 ANOVA tukey-test. b, A single optical plane of the AL illustrates that the DC4- and V-glomeruli, among others, are labeled by GC16-GAL4. c, In vivo calcium imaging of the AL of a fly carrying GC16-GAL4 and UAS-GCaMP. Arrow indicates DC4. Peak ΔF responses are shown here. Scale bars: 10μm.
